Like others, I split mine up, especially between traveling companions. It is funny to me that women are usually not thought to be carrying money if they are with a guy. That saved some folks we met in Jamaica when only the guy got robbed.
We use a regular money belt for DH to carry emergency cash, one of the under your clothes type for me to carry passports and most credit cards, and my favorite, a travel vest with a million inside pockets for most of our traveling money. Yes, the best is a little dorky, but so nice to travel without a handbag to keep up with! Get a size bigger if you want one, they need to be able to fit over your clothes when loaded down.
